Intrusive Thoughts as Determinants of Distress in Parents of Children With Cancer1

This study investigated the relationship between frequency of intrusive thoughts and susceptibility to reminiscent stimuli and consequent distress in parents of children with cancer and parents with healthy children. Cancer-related words embedded in the Stroop task (e.g., “chemo” printed in green ink), served as the reminiscent stimuli. Results indicated that frequency of intrusive thoughts reported 2 months before the experimental session was positively correlated with evoked thoughts and associated distress among parents with ill children. Intrusive thoughts predicted 11–17% of the variance in evoked thoughts and in elicited distress, whereas other symptoms of chronic stress did not predict evoked thoughts and elicited distress. Cognitive and affective task reactivity by parents of children with cancer were not accompanied by behavioral or physiological reactivity. Future research should examine the extent to which more acute and naturalistic intrusive thoughts elicit reactivity across cognitive, affective, behavioral, and physiological dimensions, and long-term physical and mental health effects associated with chronic intrusive thoughts.     

Precursors of Vocational Psychology in Ancient Civilizations

The authors examine philosophical theories produced by two ancient civilizations (Eastern Mediterranean and Chinese) for applications to an applied psychology of work and conclude that they possessed recognizably “modern” elements of an effective vocational psychology.     

Managing stress and managing illness: Survival and quality of life in chronic disease

Interest has been steadily building in the impact of stress on psychological and physiological functioning, in particular on immune system responses, furthering the concept of a strong connection between the mind and the body. Implications for prevention of disease onset or treatment of stress-induced illness or immunocompromised conditions have been explored through the implementation of stress management techniques. Cognitive behavioral stress management interventions, biofeedback, relaxation, guided imagery, hypnosis, individual and group psychotherapy, aerobic exercise, and guided self-efficacy treatment are briefly reviewed to identify possible treatment mechanisms that may affect immune function and promote quality of life. The application of behavioral techniques to reduce distress and sharpen coping skills has great promise in reducing the costs associated with chronic disease and in enhancing quality of life among those afflicted.Presented at the APA Presidential Miniconvention, To Your Health: Psychology Through the Life Span, Session VIII, Assuring a Healthy Lifestyle: Psychology Delivers.

NONCONTINGENT DELIVERY OF ARBITRARY REINFORCERS AS TREATMENT FOR SELF-INJURIOUS BEHAVIOR

Results of recent research have shown that noncontingent reinforcement (NCR) can be effective in reducing the frequency of behavior problems. In typical NCR applications, the reinforcer that is responsible for behavioral maintenance (as demonstrated through a functional analysis) no longer follows occurrences of the target behavior but instead is delivered according to a time-based schedule. Thus, it is unclear if NCR would be effective if the target behavior continued to be reinforced or if arbitrary reinforcers (i.e., those irrelevant to behavioral maintenance) were substituted for the maintaining reinforcers in the NCR procedure. In this study, 2 individuals whose self-injurious behavior (SIB) was maintained by positive reinforcement were exposed to conditions in which arbitrary and maintaining reinforcers were withheld and were delivered either contingently or noncontingently. Results indicated that noncontingent delivery of arbitrary reinforcers was effective in reducing SIB even though occurrences of SIB produced access to the maintaining reinforcer. These results suggest that (a) arbitrary reinforcers may sometimes be substituted for maintaining reinforcers, (b) an important component of NCR procedures is alteration of a behavior's establishing operation, and (c) NCR with arbitrary reinforcers might therefore be effective when maintaining reinforcers cannot be identified or withheld during the course of treatment.     

Influence of Maternal Depressive Symptoms on Ratings of Childhood Behavior

This study uses information collected on two occasions from a probability sample of families with 5- to 12-year-old children (N = 1151) participating in a general population study in 1983 and follow-up in 1987. It evaluated the importance of maternal bias in the assessment of child behavior by comparing the relative strengths of association between maternal depression and childhood behavior and between maternal depression and mother reporting errors. Conduct problems and hyperactivity were measured as latent criterion variables constructed from mother, teacher, and youth (aged 12 to 16 years) ratings and their associations with maternal depression were modeled using covariance structure analysis. The analyses revealed that maternal depression was associated significantly with conduct problems ( = .35) and hyperactivity ( = .38) among 5- to 7-years-olds in 1983 but not 4 years later in 1987. None of the associations between maternal depression and mother reporting errors were significant. Among 8- to 12-year-olds in 1983, maternal depression was associated significantly not only with conduct problems ( = .17) and hyperactivity ( = .15) but also with mother rating errors of these behaviors ( = .13 and .17, respectively). Four years later in 1987 when this cohort was 12 to 16 years old, the only significant association was between maternal depression and conduct disorder ( = .25). Although evidence exists for associations between maternal depressed mood and mother rating errors, there also appears to be a substantive association between maternal depression and childhood behavior.     

Repetition priming and face processing: Priming occurs within the system that responds to the identity of a face

A familiar stimulus that has recently been recognized will be recognized a second time more quickly and more accurately than if it had not been primed by the earlier encounter. This is the phenomenon of “repetition priming”. Four experiments on repetition priming of face recognition suggest that repetition priming is a consequence of changes within the system that responds to the familiarity of a stimulus. In Experiment 1, classifying familiar faces by occupation facilitated subsequent responses to the same faces in a familiarity decision task (Is this face familiar or unfamiliar?) but not in an expression decision task (Is this face smiling or unsmiling?) or a sex decision task (Is this face male or female?). In Experiment 2, familiar faces showed repetition priming in a familiarity decision task, regardless of whether a familiarity judgment or an expression judgment had been required when the faces were first encountered. Expression decisions to familiar faces again failed to show repetition priming. In Experiment 3, familiar faces showed repetition priming in a familiarity decision task, regardless of whether a familiarity judgment or a sex judgment had been asked for when the faces were first encountered. Sex decisions to familiar faces again failed to show repetition priming. In Experiment 4, familiarity decisions continued to show repetition priming when a brief presentation time with encouragement to respond while the face was displayed reduced response latencies to speeds comparable to those for sex and expression judgments in Experiments 1 to 3. The results are problematic for theories that propose that repetition priming is mediated by episodic records of previous acts of stimulus encoding.     

Believe it or not! longer questionnaires have lower response rates

The effects of questionnaire length on response rate and response bias were examined by conducting a mail survey of 8534 persons taking distance education courses in insurance and financial planning. In 14 replications, persons were randomly assigned to receive a long or short course evaluation questionnaire. Response rate for the short form averaged about 28% higher than for the long form, and was significantly higher in all 14 replications. A measure of course satisfaction appearing on both questionnaires showed no significant differences between the long and short form in 12 of the 14 replications. The results suggested that biased measurement of consumer satisfaction does not necessarily occur on a long questionnaire with a relatively low response rate.
